There are facts and there are realities. Yes there are too many people, it is a fact. But the reality is we are advanced enough to change how we use energy and that we have actionable solutions. Killing a few billion people is not really on the table. There is no point in spending time on a problem without a solution.
And part of that solution is talking about overpopulation. Who said anything about killing people? Oh right the Syrians. All one hears from the environmentalists are the "you shoulds". You should do this or that. I agree that there is probably the scientific knowledge to develop viable alternative energy sources and I do think that should be thoroughly investigated and developed and it will be when oil starts to cost too much. The Chinese are all over solar and I'll bet they have viable equipment before anyone else. I do think that the tax that oil companies pay should be very high. They are benefiting from a non renewable resource after all and once gone it won't be renewed in our lifetime. Their tax rate should be really high. I heard that in Norway they tax oil companies 90% plus they have their own state run oil company. Seems to work there.
